Pokken Tournament DX with new 7th Gen Pokemon.
Pokemon Ultra Sun and Ultra Moon is set to be based in an "alternate timeline" from the main games.
and finally Pokemon Gold and Silver will be released to the Nintendo 3ds eshop this fall as well, no Crystal port announced yet.

Well chances are, it's probably the same here - the "Remake team" instead worked on Pokémon Black 2 and White 2. If they make a Gen VIII or a Switch Pokémon game, who knows if they have the remake team work on a Sinnoh remake.

I'm a little surprised that these are still on 3DS rather than Switch, but at the same time, I'm not. Gamefreak has always been somewhat reluctant to move forward on platforms. (see: Gen V on DS and not 3DS)

Still, if B2W2 are any indication, I'm very much looking forward to what USUM have to offer.

The Switch audience is still growing, so in terms of pure $$$ it's better to squeeze the 3DS teet one last time. I'm sure Nintendo would like a Switch game but TPC and GF generally do their own thing in regards to the IP.

so I got Moon because MOONBAT SO PWETTY and am missing out on Sun exclusives (Want Kartana! Want to make Team AFK!) but with these new forms I actively hate the new Solgaleo design but want Sun exclusives HALP PLZ

Overall, though, like ML I liked B2W2 and am therefore optimistic. But why does Solgaleo look so stupid ;-;

Since Gen IV was actually the last time they did a "Third version" that they could incorporate features and/or subplots from (Remember how HG/SS had the Suicune Subplot?). Gen V had a full-fledged sequel.

Though the question would be, would a Gen IV remake have the distortion world.... or have it be Giratina while you can obtain Pakia and Dialga other ways?
